VENTILATOR.

Specification of Letters Patent.

ratenteol March 12, 1907.

Application filed August 27, 1906. Serial 110.332.15 1

T0 at whom, it may concerm Be it known that I, FREDRIOH J KoBUsoH, acitizen of the United States, and a resident of St. Louis, Missouri,have invented certain new and useful Improvements in Ventilators, ofwhich the following is a specification containing a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to a ventilator particularly adapted for the upperends of flues and ventilator-pipes; and the object of my invention is toconstruct a simple inexpensive ventilator which combines strength anddurability with light weight.

To the above purposes my invention consists in certain novel features ofconstruction and arrangement of parts which will be hereinafter morefully set forth, pointed out in the claims, and illustrated in theaccompanying drawings, in which Figure 1 is a vertical section takenthrough the center of a ventilator of my improved construction. Fig. 2is a horizontal section taken on the line 2 2 of Fig. 1. Fig. 3 is ahorizontal section taken on the line 3 3 of Fig. 1.

Referring by numerals to the accompanying drawings, 1 designates thebody of my improved ventilator, which is in the form of avertically-disposed cylinder which tapers slightly toward its lower endand which lower end is tapered to be fitted onto the top of a chimney oron the upper end of a ventilator flue or pipe.

Rigidly fixed to the upper end of the cylindrical body 1 is asheet-metal member 2 in the form of a truncated cone, and fixed to theupper end of said member 2 is the lower end of a circular wall 3, ofreticulated material. Fixed to the upper end of said reticulated wall isa ring 4, and supported thereby is a conical member or cap 5, thediameter of which is somewhat greater than is the upper end of thecylindrical body 1. Rigidly fixed to the upper end of the body 1 is theupper end of a sheet-metal ring 6, the lower end of which is somewhatsmaller in diameter than is the upper end, and formed through said ringadjacent its upper end is a row of apertures 7. Fixed to the lower endof the ring 6 and extending upwardly therefrom is a series of standards8, which support a conical deflector 9, which is concentrically arrangedwithin the body 1 and with its lower end in approximate horizontalalinement with the row of apertures 7. Depending from the lower end ofthe ring 6 is a series of straps 10, which support a conical deflector11,similar in size to the conical deflector 9 and concentricallyarranged in the lower end of the body 1.

I/Vhen my improved ventilator is in use, the smoke and gas or foul airrising through the chimney or ventilator pipe passes into thecylindrical body 1, and, striking against the deflector 11, is thrownthereby outwardly against the wall of the body 1, and from thence thesmoke, gas, and air pass upwardly outside the ring 6, through theapertures 7, upwardly through the truncated conical top 2, and finallydischarges through the reticulated section 3 to the atmosphere. Anysmoke, gas, or air which may pass upwardly through the lower end of thering 6 strikes against the deflector 9 and is thrown or deflectedthereby outwardly and upwardly.

The cap 5 effectually prevents rain and snow from entering thereticulated section 3, and said reticulated section prevents birds fromentering and nesting in the ventilator, and where the ventilator islocated on the upper end of a ventilator-pipe said reticulated sectionprevents sparks from adjacent chimneys entering the ventilator andpassing downwardly therethrough.

Aventilator of my improved construction is simple, inexpensive, is verystrong and durable, can be very cheaply manufactured, and is veryeflicient in use.

I claim 1. A ventilator, constructed with a cylin drical body, aperforated ring fixed in the upper end thereof, conical baffle membersarranged on the interior of the body, a truncated conical top fixed onthe body, a reticulated section arranged at the upper end of said top,and a conical cap supported above the reticulated section; substantiallyas specified.

2. A ventilator, constructed with a cylindrical body, a ring arranged inthe upper end thereof, there being a row of perforations formed in theupper end of said ring. conical baflle members concentrically arrangedin the cylindrical body above and below the ring, a top arranged on thecylindrical body, having an open upper end, a reticulated sectionarranged around the open upper end of the top, and a cap arranged abovethe reticulated section; substantially as specified. y

3. A ventilator, constructed with a cylindrical body, which graduallytapers toward its lower end, a ring fixed in the upper end of saidcylindrical body, Which ring tapers toward its lower end, there being arow ofperforations formed in the upper end of the ring, conical bafiiemembers supported above and below the ring, a truncated'oonical top forthe cylindrical body, a reticulated section fixed to and surrounding theupper of the truncated conical top, and a conical cap supported by thereticulated section and 1 covering the upper end of the top of thecylindrical body; substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
